BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Begonia plant, botanically known as Begonia boliviensis X Begonia tuberhybrida, commonly referred to as a Hybrid Tuberous Begonia and hereinafter referred to by the name ‘BeTesorang’.

The new Begonia plant is a product of a planned breeding program conducted by the Inventor in Heerhugowaard, The Netherlands. The objective of the breeding program is to create new vigorous and strong Begonia plants with numerous attractive flowers and good garden performance.

The new Begonia plant originated from a cross-pollination on May 30, 2014 of a proprietary selection of Begonia boliviensis X Begonia tuberhybrida identified as code number 13-551-07, not patented, as the female, or seed, parent with a proprietary selection of Begonia boliviensisX Begonia tuberhybrida identified as code number 13-489-14, not patented, as the male, or pollen, parent. The new Begonia plant was discovered and selected as a single flowering plant from within the progeny of the stated cross-pollination in a controlled greenhouse environment in Heerhugowaard, The Netherlands on Nov. 21, 2014.

Asexual reproduction of the new Begonia plant by vegetative terminal cuttings in a controlled greenhouse environment in Heerhugowaard, The Netherlands, since Dec. 14, 2014 has shown that the unique features of this new Begonia plant are stable and reproduced true to type in successive generations of asexual reproduction.

SUMMARY OF THE INVENTION

Plants of the new Begonia have not been observed under all possible combinations of environmental conditions and cultural practices. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘BeTesorang’. These characteristics in combination distinguish ‘BeTesorang’ as a new and distinct Begonia plant:

-   -   1. Uniform, upright to broadly outwardly spreading plant habit.     -   2. Freely branching habit.     -   3. Dark green-colored leaves.     -   4. Freely flowering habit.     -   5. Single-type female and male flowers that are bright orange in         color.

Plants of the new Begonia can be compared to plants of the female parent selection. Plants of the new Begonia differ primarily from plants of the female parent selection in the following characteristics:

-   -   1. Plants of the new Begonia are more freely branching than         plants of the female parent selection.     -   2. Flower tepals of plants of the new Begonia are straight         whereas flower tepals of plants of the female parent selection         are reflexed.

Plants of the new Begonia can be compared to plants of the male parent selection. Plants of the new Begonia differ primarily from plants of the male parent selection in the following characteristics:

-   -   1. Plants of the new Begonia are more freely branching than         plants of the male parent selection.     -   2. Plants of the new Begonia have larger and darker green leaves         than plants of the male parent selection.     -   3. Flowers of plants of the new Begonia are bright orange in         color whereas flowers of plants of the male parent selection are         orange and white in color.

Plants of the new Begonia can be compared to plants of the Begonia pendulaX Begonia boliviensis ‘Encanto Orange’, disclosed in U.S. Plant Pat. No. 20,898. In side-by-side comparisons, plants of the new Begonia differ from plants of ‘Encanto Orange’ in the following characteristics:

-   -   1. Plants of the new Begonia are more rounded than plants of         ‘Encanto Orange’.     -   2. Plants of the new Begonia have darker green-colored leaves         than plants of ‘Encanto Orange’.     -   3. Flowers of plants of the new Begonia have shorter tepals than         flowers of plants of ‘Encanto Orange’.

Plants of the new Begonia can also be compared to plants of the Begonia boliviensis ‘Bonfire’, disclosed in U.S. Plant Pat. No. 15,108. In side-by-side comparisons, plants of the new Begonia differ from plants of ‘Bonfire’ in the following characteristics:

-   -   1. Plants of the new Begonia have larger and darker         green-colored leaves than plants of ‘Bonfire’.     -   2. Plants of the new Begonia have larger flowers than plants of         ‘Bonfire’.     -   3. Flowers of plants of the new Begonia have shorter tepals than         flowers of plants of ‘Bonfire’.

BRIEF DESCRIPTION OF THE PHOTOGRAPH

The accompanying colored photograph illustrates the overall appearance of the new Begonia plant showing the colors as true as it is reasonably possible to obtain in colored reproductions of this type. Colors in the photograph may differ slightly from the color values cited in the detailed botanical description which accurately describe the colors of the new Begonia plant. The photograph is a side perspective view of a typical flowering plant of ‘BeTesorang’ grown in a container.
